7G DOHC headswap.... The easy way! ???

[thebirdman13]

i wonder if this method would cross over to the 8g v6 using 3kgt heads?
i bet it would.

just imagine,
a 3.5l(diamante motor) DOHC stroker in a 8g....
mmmmm
talk about a powerband.

congrats on a job well done.</span>
:thumbsup: :thumbsup: :thumbsup: :thumbsup: :thumbsup: :thumbsup: :thumbsup:

well, the internals fit in the V6... i'm sure the head could be swapped somehow... maybe i could work on this when i move back to PA in the spring and actually have a garage to work in...

werd, anything is possible

I am kicking myself in the butt for not thinking of this and doing this at the time I turbo'ed the car.

BTW: You used a 4G63 timing belt right and the 4G64 spark wires right?

i'm pretty sure the 63 timing belt doesn't fit on the 64DOHC due to the extra deck height. this is a problem with guys building the 7bolt 2.4 vs the 7bolt 2.0

From my knowledte, you use a 4g64 DOHC timing belt and cam gears(for the timing marks).

i know you can swap the cam gears over, but you need to remark the tdc mark on them, i believe it's 1.5 teeth off?

How did you plug the extra oil gallies on the block? I hope you didnt forget this step :)

so if a guy were to go out and get a dohc head, which oil galleys would they need to plug before putting the head on.

pics please.

you do know... this changes everything :twisted:

you do know... this changes everything :twisted:

yes its an upgrade,
but still,
if i were you i woudl continue along your same path,
although this mod is a fairly simple and painless way to get a significantly higher power out of your 4g64,
there is still no substitute for a knock sensor, distributorless ignition, and a turbo or galant gs ecu.

you can still boost this setup, but the mechanical and tuning limits are the same as with the 7g sohc, however you of course will make more pwoer across a greater powerband with this setup, turbo or no.

by all means, if you desire, go ahead and boost yoru motor with the dohc head.

but i mean,
you are already so close to the 4g63t setup, why cut yourself short at this point,
all you need is a little wiring.



but to everyone else,
if you seriously want to add some power and capability to yoru engine,
do this mod.
just think about the new levels of power you can run....
now that you ahve a 4g63 head,
you can get cams, valves, valvesprings, camgears, different intake manifold options...
all for the 1g or 2g eclipse turbo!
that means you can get used parts fopr CHEAP off ebay or tuners and increase your power.

i imagine this setup with some cams and a good tune could get you into the 13's without a lot of hassle, or any boost.

those of you that are more willing to drop the dime... could see 12's!

you guys are goingto hate me for this but i cant wait till the first dohc galant(this way) finishes......well im actually wondering if you guys can write the materials needed for this.....i'm asking for the list because im really considering on doin this on one of my 7g's....thanks.....




crap never mind i didnt see the website...im so sorry

[DOHCstunr]

well well well sorry to frustrate u guys and i had a shop tap the holes and plug them so they are flush with the block i would have been pissed if i forgot that step!!!! :-P welll all is good she is up and running havent really done any eal tests yet just drover her round the block a few times and checked for leaks but is sounds good it idles good and it looks great, power gains, i can feel that they are there when i take off but im just tryin to get the head used to the block i dont want to fuck up my headgasket by drivin it real hard yet but so for no problems and the best part started up the first try no check engine light on or nothin no leaks, the distributor seems to be working good so i can safley say it was succesful but ill let u know how the power gain is im gonna drive it nice and easy for a few days then once im ready to risk all my good work and time and money i put into this project im takin it to the the track!!!!!! thanx u guys

Ok...today I did some packing up getting ready to move into my house. Well I finally found my distributer from my 95 Galant. I went ahead to fit things to my spare 1g 4G63 DOHC cylinder head:

The 7g distributor doesn't fit. :-? I compared the 1g CAS to the 4G64 SOHC distributor there is a big difference.
First off the distributor shaft where on a SOHC 4G64 head it would just slide into the cylinder head and the rotor slot wouldn't fit into the end of the camshaft. Well the 7g distributor shaft is too wide to even fit into the 63 DOHC head. So basically...the rotor slot won't reach the end of the intake camshaft and no way it would seal or even bolt it to the head.

Basically it won't fit...or at least I can't get it to fit, I don't see how. I don't know if its just the 94-95 distributor are different from 96-98, but I don't think that would make a difference.

Fast...please post pics on what you did to make the distributor fit into the DOHC head, because I don't see how you did it. I wish I had a digital camera to show what I am talking about

[Proto]

the 94-95 are diff from the 96-98 distribs.

[4-G-rim]

the 94-95 are diff from the 96-98 distribs.

Well..yes, I should of clarified myself. I know the actual rotor and cap are different from the 94-95 vs 96-98 distributors. What I was referring to was the shaft that goes into the cylinder head.
